The growing awareness of the health impacts resulting from exposure to a wide range of compounds has led to the strengthening of environmental regulations and policies, such as Ordinance GM/MS No. 888, of May 4, 2021. In recent years, the search for effective ways to reduce environmental impacts has become even greater, since the risk of contamination of water resources is an environmental concern with a major impact on public health. Therefore, the study aims to evaluate and characterize the quality of groundwater, determining some physical-chemical and microbiological parameters. Five wells were selected, where the variables of pH, turbidity, electrical conductivity, color, temperature, alkalinity, total hardness, calcium, magnesium, chlorides, acidity, total coliforms and thermotolerant coliforms were analyzed. Microbiological analyses were performed to assess the presence or absence of total and thermotolerant coliforms. Subsequently, field and laboratory tests were carried out. The results obtained during the tests indicated that the analyzed waters require different treatments, inherent to their specific quality. Well 02 meets all the standards of Ordinance No. GM/MS 888/2021, however, it operated for only 3 months during the year. Samples from wells 01, 03, and 04 meet the various aspects of the ordinance, requiring only chlorine treatability to meet all potability regulations. Well 05 does not meet all the standards of Ordinance No. GM/MS 888/2021, demonstrating samples that exceeded the VMP for turbidity, color, total hardness, and chlorides.ptMonitoramentoRecursos hídricos3.
